This invention relates'to hoists 'designed for use in the freighthandling systems especially adapt-ed for use in freight stations and itsprincipal vobject is to facilitate' the transfer of freight from onefreight station to another. These systems ordinarily have a series oftrucks with removable boXI bodies',-

said bodies being taken off the truck by'a hoist and deposited by the'hoist inthe de'- sired position in the freight house where it is loadedand then placed'upon the truck by the hoist. For the efiicient operationof such systems it is necessary for all freight stations inthe city tobe equipped with the syst-em. Then a truck will bring a kload of freightfrom one freight station to the other where it is taken off the truckand another loaded body is placed thereon to be returned yto the firstfreight station. In this way the trucks do not have to wait for theloading` andunloading, and alsothe body can be taken to the Vfreightitself instead of Wheeling yand carrying the freight to the body.

This system has been installed in Avarious places and is proving verysatisfactory.

As stated above, this invention is animproved hoist or crane forremoving from or placing on said trucks thebodies oi' boxes in which thefreight is loaded; In order to do this satisfactorily the hoist must beso designed that it will notonly lift the bodies and carry them fromplace to place, but it also must be so designed that the body can berotated through a' few degrees so that it'can be placed in the correctposition upon `the truck without any trouble. As will be read'- ilyseen, if the hoist or crane were not capable of giving the body a slightrotation the truck upon which it is to be deposited would have to vbeparked directly under the hoist and eXact-ly parallel to the sidesof thebody carried by the hoist. can rotate the body a few' degrees noparticular care need be taken in positioning the In the drawingsFigyl isa top plan view of the apparatus; Figs, 2, 3 and 4 are sections on thelines 2;-2, 3 3 and respectively, of Fig. 1, and Fig. 5 isa section onthe line 5-5 of'Figg2.

Two spaced lrails 1 and'2 upon whichv the hoist or cra-ne rides (whichrails vmay be built up the channel irons and plates as shown or may beordinary I-beam) are suspended direction of 'rotation of the shaft'f20.However, if .the 4hoist from the ceiling of rthe building. The'vhoistorcrane comprises two pairs ofchannel irons 3 and 4 Vand 5 and 6, thechannel irons 3 and 4be-ing Vplacedon vopposite sides 4of the rail 1 andconnected across the' bottom bycross. pieces 7,' and the channels 5 and'6` being vplaced on opposite sides ofthe rail 2 and connected acrossthe bottom by cross pieces 8. The channel irons 4 and 5 are connectedtogether by cross beams 9, 10, 11 and 12.l

The channel' irons 3', 4, 5 and A6 have ate.

tached thereto studs 13 and 14, the studs 13 having rotatably mounted-thereon track vwheels 15,'which ride on the iianges ofthe rails 1 and2, and roller or ball bearings 16 between the rear faces ofthe trackwheels 15 and the channelirons 3, 4, Sand 6. i IThe studs 14 haverotatably mounted thereon track wheels 17 to which are rigidlyattachedgears 18. Roller bearings 19 similar to the bearings 16 are placed'betweenthe gears 18. and the channel irons 3, 4, '5 and 6. V

lA shaft 20, carried in bearings" 21 at# tached tothe lower flanges ofthechannel irons 3,4, 5 and 6, has gears "22' thereon which mesh withthe gears 18. Onelend of the shaft 21 has mounted thereon a wheel 23which carries an endless chain'or-'cable'24 by which the shaft 2O isrotated by a person'on the'floor. It is to be understood that .if sodesired the wheel v23 and cable or chain 24 maybe placed on either orboth ends of the shaft 20 as desired; also the shaft r20 may be rotatedbyv a motor carried by the frame, if it is desired to do so. By rotatingthe shaft 20 the gears 22 and 18' and consequently the track wheels 17'are rotatedvwhichwill cause the frame carried -by vthe wheels 15 and'17 to be moved along the tracks 1 and 2, vthe direction of the movementd ependingup'on the A shaft 25 is carriedr in'brackets26 depending fromthe lower flanges of the channels 3, 4, 5 and 6 midwayfbet-ween thestuds 13 and 14. Drums Y27 are `vsecured to A'the shaft^25 near the'endsthereof beneath lthe rails 1 and 2. The shaft '25 is rotated-'by a motor28 (carried on cross beams 29vextending between the beamsy 11 and 1 2)4through gears30 and 31 and a worm gear reduction carried ina housing 32ksuspended from 'the cross bars' 10 and `1l.l 33 indicates'shaftcouplings.

` Four "frames, A'generally denoted by* 3 4 vertical end members 36 an6. As is clearly shownin the drawings, the

which consist of horizontal to jinembers 35, intermediate members 37,parallel to the end members 36 and lower horizontal connecting members38 whichv connectthe'lower ends of y.the inem-V ber's 36 and 37, areslidably mounted upon `the roller bea-rings 16 and 19 between the wheelsand 17 and the channels 3, 4, 5 and lower members 38 of the fra-mes 34are con c nectedV by shafts l39 and40, the shafts B9 carrying sheaves41and thel shafts 40 carryingsheaves 42. As will be seen'bythe drawingsthesheaves 41: are yin alignment with each other, and the sheaves 42 arein alignment with each other. Y `cross ieces 7 and 8 are eyes 43Y towhich one Depending from the end-o cables 44 is secured, theother endsof said cables being secured to the vdrum 27 and Wound thereon inopposite directions as islshown fclearly in Fig.r The cables 44 runfromfthe drum 27 and over the sheavesv 42;,- thence f downwardly. andaround the sheave wheels 45 which carry sheave blocks 46 and thenceupwardly and over the `sheaves 41 jand thence to the eyes 43 vwhere theyare v34 mounted between the tracks 1 andv 2. As

will be Vnoted in Fig. 2, thefrack 50 is below the gear 49 while therack 502L is above the gear 49". The shaft 47 is rotated by a wheel 51and endless chain orcable'52, said wheel 1 and chain being similar tothe wheel and chain 23 and 24 respectively. l/Vhen the shaft 47 isrotated, the opposing pairsof frames 34 will be lcaused to move inopposite direc- 45 tions by the gears 49 and 49 and racks 50 1Q and 50a.The frames '34v will move easily,

due to the fact that they are mounted on the roller bearings 16 and 19..VThe shifting of the framesl 34 will not affect the height of thesheaveblocks 46 as the distances between the fixed ends of the cablesare always constantv no matter what positions the frames are in. c

AIn operation the device is used as follows: The hoist or crane isbrought over the box or body to be moved, (said bodybeing indicated ,indot and dash lines in Figs. 2 and) by rotating-the shaft 20, gears 22and 18 and conse uently the track wheels 17. Then it is broug t, overvrthe body, the shaftV 25 and consequently the drums 27 are rot-ated bythe motor 28 and interposed gearing which allows the four sheave blocks46 to be lowered until they are fastened to hooks carried by the body orbox. Then the shaft 25 is roftated in the opposite direction whichraises it from the truck or floor as tliecase Amay be and it is carriedto the place desired.

lowering the box, if any angular movement is" desired, this issecured'by rotatingy the shaft 47 which' will move'the frames llidi-andconsequently the sheave blocks 46 Vin opposite directions which willgive a slight angular movement .to the box or body carried by the blocks46.

' It will be' seen that,bytheineansdescribed I have provided forshiftingthehoisting cables longitudinally with respect 'tol fthemaintrack of the crane, the cables atkoppoi site sides being VshiftedVin oppositekrdirections, so that'a box or load suspended by the cableswill be sl ewed,'iiioi'e or lesswith respect to the line of travel ofthecrane and y will thereby be disposed in an angular posi-l tion so that`it may be lowered inproper position on a` truck, even if the latter isnot'.

located in a position exactly parallel to. theV travel of the crane.This resultis particularly desirable in installations .of this kvindwhere the` load is suspendedat four points. A load suspended from asingle point can of course be quite readily turned- `by hand, but thiswould be attendedwithsome didiculty in a crane of the present type. Bythe invention disclosed this 'turning or skewing -f 1.
